String Comparison shows error on String retrieved from flash[:alert]

Question

I am having a javascript code to compare two strings and execute code accordingly.

One String retrieved though rails flash[:alert] and other specified locally.

     <% if flash[:message].present? %>
         var message=new String("<%= flash[:message] %>");
         var message_status=message.localeCompare("mail_sent");
         if(message_status==0)
         {
           // if code....
         }
         else
         {
           alert(message);
           // else code....
         }
    <% end %>

Here, ultimately, i am trying to compare two Strings. One retrieved through flash[:alert] and other specified locally i.e mail_sent.

What I observe is

It always goes through the else part even though the message displayed in the else part alert is mail_sent.

Please Note that when i replaced the <%= flash[:message] %> with String locally. It executed the if part. i.e

var message=new String("mail_sent");

instead of

var message=new String("<%= flash[:message] %>");

Could anyone say why is it so ?

What is need to be done in order to compare two strings in this way?

Answer 1

please check your controller. There might be something wrong there. Are you sure you are setting flash[:message] ="mail_sent" ????
